feat: implement advanced image editing with drop zone and staging workflow

Completely redesigned image editing experience with professional workflow:

## 🎨 New Drop Zone Interface
- **Drag & Drop Support**: Users can drag image files directly onto preview area
- **Visual Feedback**: Border changes to green on dragover, overlay shows drop instruction
- **Click to Select**: Alternative file selection by clicking the preview area
- **File Type Validation**: Supports JPG, PNG, GIF, WebP with proper validation

## 📝 Staging System (Non-Destructive Editing)
- **No Immediate Changes**: Image replacement and alt text edits are staged, not applied immediately
- **Change Tracking**: Visual indicator shows when user has unsaved changes
- **Preview Updates**: Users see staged changes in real-time preview without affecting document
- **Staging State**: Maintains separate staged vs. current state for both image source and alt text

## 🎯 Enhanced Button Workflow
- **Accept**: Applies all staged changes (image + alt text) to document content
- **Cancel**: Discards all staged changes and closes editor
- **Reset**: Clears staged changes and returns preview to original state (keeps editor open)

## 🚀 User Experience Improvements
- **Professional Interface**: Clean, modern design with clear visual hierarchy
- **Immediate Feedback**: Real-time preview of changes without document modification
- **Non-Destructive**: No accidental overwrites - changes must be explicitly accepted
- **Intuitive Controls**: Standard edit/cancel/reset pattern familiar to users

## 🔧 Technical Enhancements
- **Memory Efficient**: Removed redundant replaceImage method, integrated into main editor
- **Event-Driven**: Proper drag/drop event handling with prevent default
- **State Management**: Comprehensive staging state tracking with change detection
- **Error Prevention**: File type validation and graceful error handling

Added comprehensive test suite with 7 tests covering all new functionality.
All image editing workflows now provide professional, non-destructive editing experience.
